1'0 all w/tom it may concern:

Be it known that I, FRANKLIN B. Snos'rna, a citizen of the United States, and a resident of New Haven, in the county of New Haven and State of Connecticut, have invented cer tain new and useful Improvements in Fire Straightening and Cutting-Off Machines, of which the followingis a specification.

My invention relates to wire straightening and cutting-off machines.

The object of my invention is to construct a machine of this character that will combine ethciency, simplicity, durability, and cheapness; that can be easily assembled and taken apart and packed for shipment so as to oc cupy but little space as compared with the present machines now in use, and, further, that the machine can be extended or added to, so as to cut lengths of wire beyond the capacity of the ordinary compact machines; further, the head carrying the wire-straightener and cutter-holder can readily be detached from the bed or table and used ex elusive of the guidebar.

To enable others to understand my invention, reference is had to the accompanying drawings, in which Figure 1 represents a front side elevation broken view of the table guide-bar, and its supporting-bar, and sectional view of the weighted lever-beam that actuates the lower feed-roll box, also broken view of the table extension. Fig. 2 is afront end elevation of the machine-head and broken view of the weighted lever-beam. Fig. 3 is a sectional elevation of the machine-head through line a c of Fig. 1 with the cutter-holder removed.

Fig. 18 is a detail perspective view of the reversible wirecuttcr. Fig. 19 is a broken view of the machinehead, showing the cutting-dies in place. Fig. 20 is a broken view of the cutter-holder, show ing a modified construction whereby it actuates the guidebar. Fig. 21 is a reduced broken detail view ol a modified construction 01' the cutteeholder adapted to slide on the machine-head. Fig. 22 is a broken sectional view of the machine-head and a front elevation of the modified cutter-holder shown at Fig. 21. operatively mounted therein.

Its construction and operation are as follows:

1 represents the bed or table, which in most cases and as a matter of economy consists of a wooden plank.

2 is the machine-head, 3 an ordinary rotary wire-straightener head, and 4 its frame, I

crum-points 9 located at the rear of said box and engaging the upper and lower walls of the square hole 10 of the head 2. The upper shaft 8 is the driving-shaft and carries at its outer end the combined balance and driving pulley 11. This pulley carries the cam 12, adapted to actuate the cutter-holder 13 pivotally supported on the stud 14 projecting from the head 2, presently to be more fully described. When the wire 'A is being fed forward, the feed-rolls are in close relation with each other, as shown at Figs. 1, 3, and 13 and are held there until the wire is severed, as follows: 15, Figs, 1, 2, and 3, is a lever carrying the movable weights 16. .17 is the head portion of this lever, which is ournaled in the U-shaped bearings 18, project ing from the inner face of the spotting-piece 4 and the inner face of the flange 2 of the head 2.

therefrom is the toe 19, adapted to engage the projection 9 of the box 9,. and shown dotted at Fig. 3. is a short arm projecting from the head of this weighted lever, and it carries at its free end the adjusting-screw 21, adapted to be engaged by the short arm 22, Fig. 2, of the cutter-holder 13, so that when said holder is thrown back and out of cutting position the weighted lever will keep the lower feed-roll 6 up against the wire to feed it forward; but in the forward movement of this cutter-holder when severing the wire the arm 22 will strike the adjusting screw 21 and tilt the weighted lever and also permit the box 9 to tilt and carry the lower feed-roll down and out of contact with the wire, and thus arrest the further feeding of the wire until the cutter-holder has retreated suflicient to permit the feeding of the wire. Thefeed-rolls have each four grooves, adapt- .ed to feed wire of different sizes by simply changing their position, as follows: The inner groove f (see Fig. 6) is supposed to be in action or on the feeding-line of the wire. If the groove 9 is required, the collar 23, which collar may be the width of one of the grooves, is removed and placed in front of the roll, which will bring said roll up against the shoulder 2 of the machine-head. If the groove 'i is required, the collar 23 is replaced against said shoulder and the roll reversed. The groove 71 can be utilized by removing said collar from its inner position and the roll brought against the shoulder 2 as before mentioned. This construction of the rolls, whereby several different sizes of grooves are inclined face 243.

Integral with the head portion of this weighted lever and projecting upward combined in one roll, is of great advanta e in that there is only one roll required, whi e in ordinary cases a separate roll is required for different sizes, which often results in these rolls being misplaced when most wanted. It will be understood, however, that a multiplegrooved roll can be used when all of the grooves are of the same size, so that when one groove is worn out another groove can be brought into position.

The automatic arrangement for temporarily arresting the feeding of the wire by drop-. ping the lower feed-roll is especially adapted for wire of small diameter. Where large wire is used, the device shown at Fig. 13 is employed. 24 is a bracket seated on the lower edge of the square opening 25 of the machine-head, (see alsoFig. 1,) having the 26 is amovable blockhaving a tapered foot adapted to slide on the inclined face of said bracket, while its upper end engages the lug 9 of the box 9. 27 is an adjusting-screw engaging a threaded hole in said block, whereby said block is moved in and out by means of the handle 27 a of said adjusting-screw. In this construction the box 9 would be manually operated to raise and lower said box.

The reversible wire-cutting dies (shown at Fig. 17) comprise the two sections 28 and 29, having the grooves jlc mn, and are inserted in an openingin the upper part of theflange ortion 2 of the head 2. (Seen more clear y at Fig. 2.) 30 is a cap adapted to hold these dies in place in the following novel and economical manner,viz: 2 is an enlarged portion of the flange 2 and is provided with an undercut to receive oneend of the cap 30, while the opposite end of the cap is secured by the screw 31.

The cutter-holder 13 oscillates, as before mentioned, on the stud 14, projecting from the head 2.

32, Fig. 18, is a solid cutter with four sides, and in each are the grooves 0 p q at, which grooves may correspond in size to the four grooves of the cutting-dies 28 and 29. This solid cutter is secured at the upper corner of the holder 13, as shown at Fig. 2, and is secured in place by the cap 33 and screw 34. This cap," like the cap 30 of the cutting-dies, has one end inserted in an undercut of the enlarged portion 13 of the said cutting-off lever. Making the wirecutter square and solid with wire-grooves in each face is a decided improvement over the present method of making cutters for machines of this character, as they can readily be reversed for different sizes of wire, or the groovesmay be of equal size, and then it has the advantage of being compact. The greatest advantage of this solid construction is the ease with which the cutter can be sharpened, as all that is nec essary is to grind the ends until the corners or edges of the grooves are sharp, and when one end is dull the cutter can be reversed without loss of time.

The cutter-holder carries the spring-actuated driver comprising (see Figs. 4 and 5) the pin 35, reciprocally operating in the hole 36 and backed up by the spring 37. This pin operates in conjunction with the cam 12 to throw the cutter-holder forward to cut off a section of wire, as follows: This cam is shown as integral with the driving -wheel 11, although it can be separate. The cam rotates in the direction of arrow 7', Fig. 5, and when the projection 38 of the cam has reached the pin 35 it will force it back and lock it in this position by means of the lockingbolt 39, having a reduced upper portion adapted to be forced into the circumferential groove 40 of the driving-pin by the spring 41. Then said pin is thus locked, the cutterholder is in its extreme rear position against the adjusting-screw 42, Fig. 2, mounted in the lug 43 of the machine-head and is held back by the spring 44, which spring has one end located in the head 2 and the other bearing against the lug 45 shown at Figs. 2 and 4.

46, Figs. 1, 2, 4, and 5, is a bell-crank lever pivotallysupported on the cutter-holder and having a groove in its horizontal arm to embrace the pin 47 of the locking-bolt 39. 43 is a trip-wire attached by one end to the ver tical arm of this bell-crank lever, and the other end is connected to the stop-rod mechanism located at the rear of the machine, as

shown at Figs. 8 and 12..

49 is the stop-rod, whichextends into the longitudinal wire-groove .9, located in the lower face of the guide-bar 50, as shown at Fig. 7.

51 is an arm secured to the short shaft 52, Fig. 12, which shaft is adapted to have a longitudinal movement in the upper end of the rear wire-bracket 53. The opposite end of this arm is forked to straddle the stop-rod, Fig. 8, and 54, Fig. 12, represents adjustable collars on said rod with the free end of the arm 51 between them.

The tripwire 48 is attached to the end of the movable shaft 52, so that when the wire has been fed into the groove of the guidebar until its forward end touches the stop-rod 49 said rod is pushed back and carries with it the movable shaft 52, which action will exert a pull on the trip-wire to actuate the bellcrank lever and draw down the locking-bolt '39 and release the driving-pin 35, which pin will be thrown forward by its spring against the flanged portion 12 of the cam 12, which flange acts as a stop to prevent the pinfrom being entirely ejected from the cutter-holder. When the driving-pin is in this position, its cylindrical surface will be in contact with the cam-surface 12 (Shown at Figs. 1, 2, 3, and 5.) This engagement will throw the cutterholder forward to sever the wire and at the same time compress and store up sufficient cam has reached the position shown at Fig. 5,

as before mentioned, the driving-pin will be forced back and locked in readiness to be again projected forward through the movement of the trip-wire.

The guide-bar 50 is adapted to have a lateral movement on its supporting-bar 51 through the medium of the screw 55, Figs. 1 and 2, adjustably mounted in the lug 56, projecting from the cutter-holder 13. When the forward end of the wire strikes the inner end of the stop-rod to release the drivingpin carried by the said holder, and this holder is impelled forward and severs a length of wire, the point of the adjusting-screw 55 will strike the rear face of the guide-bar and move it laterally on its supporting-bar, Fig. 9, until the wire-groove s therein has been uncovered sufficient to let the severed wiresection drop into the wire-receiving brackets 53, 57, and 58, Fig. 1. The guidebar is operatively supported on its supporting-bar as follows: 59, Figs. 1, 7, and 12, represents links pivotally supported on the studs 60, projecting from the upper surface of the wire-receiving brackets 53 and 57. The other ends of these links are pivotally supported on the studs 61 projecting from the upper surface of the guide bar 50. 62 represents arms adjustably secured to the studs by the setscrews 63, and 64 represents springs connecting the free ends of these arms with the studs 61. These springs serve to bring the guide-bar back to its normal position after it has discharged the wire, and the links 59 serve to keep the guide-bar parallel with its supporting-bar, and the tension of the springs is increased or decreased by simply changing the position of the arms 62 on their suppe ts.

65, Figs. 1, 10, and 12, is a clamp adjustably secured to the supporting-bar 51 and is adapted to prevent the guidebar lifting from the supporting-bar by means of the overhanging lip 65*. This clamp is always located just back of the forward end of the stop-rod 49, Fig. 12, so as not to interfere with the free discharge of the wire-section from the guide-bar. As the guide-bar is held on the supporting-bar by the arms 62, it would drop therefrom the instant these arms were removed. To prevent this, the under side of the links 59, Fig. 12, are furnished with the projections 59, which projections will strike against the snpporting-bar 51 and arrest the further movement of said levers. This feature is very important, especially when the machine is being taken apart for shipment. The supporting-bar is provided with holes adapted to receive the short studs 66, Figs. 7, 9, 12, and 15, from which they are easily removed when the machine is taken down.

In Fig. 15 is shown a modification of'the construction relating to the parallel movement of the guide-bar on its support. In this construction the weighted lever 67 is used to take the place of the links 59, arms 62, and the springs 64, previously described. This lever is pivotally supported on the studs of the wire-receiving brackets and also on the studs 61 of the guide-bar. This weighted lever has the projection 67 which serves the purpose as the projections 59" of the links 59, before mentioned.

As the guidebar or its mechanism is not directly'attached to the machine-head, the feet 57 of the wire-receiving brackets are provided with the slots 57 in order that these brackets may readily be shifted on the table 1 to bring the wire-receiving groove of the guide-bar in line with the cutting-dies.

As before mentioned, the table 1 can be made of wood or iron and as a matter of economy wood is preferable. The head 2 is simply attached thereto and can readily be removed and used for cutting off short sections of wire. In this case any suitable means may be attached to the head to serve as a gage to cut the sections of equal length.

The table 1 can readily be extended to any desired length by simply placing the extensiontable 1 Fig. 1, to the table 1, and these extensions can be multiplied indefinitely, and whenever the table is extended the guide-bar and its operating mechanism must also be extended. In other words, the guide-bar and its mechanism, together with the wirereceiving brackets, must be duplicated for every table extension that is attached. To move the second guide-bar 50*, Fig. 15, in unison with the first or initial guide-bar 50, I employ the collar or clamp 68, which is secured to the end of this second guide-bar by means of the screw 69. 68 is a projection of this collar, which extends over and embraces the rear end of the guide-bar 50, so that when this latter guide-bar is laterally actuated the second guide-bar will also be carried with it. Each and every guide-bar extension that is added to the first or initial guide-bar may be equipped with either the links, arm, and spring shown at Fig. 12 or with the weighted lever shown at Fig. 15. Whenever an extension is added, the stop rod mechanism comprising the shaft 52 and arm 51 will of course be shifted to the last one of the series of wire-receiving brackets and the stop-rod lengthened accordingly.

As the guide-bar iskept in parallel relation with its supporting-bar by means of the links 59 and the weighted lever 67, which-is also a link, the bar moves both laterally and longitudinally, but principally laterally. Therefore, as the lateral movement is the essential one and the longitudinal movement is only an incidental feature of the link connection, I wish it distinctly understood that the term Fig. 20 could be used, which consists of the overhanging projection 73 of the cutter-- holder 13, having the recess 73 to receive the end of the guide-bar 50. When this construction is used, there is not as good an opportunity to adjust the position of this recess with respect to the guide-bar or said guide-bar with respect to the feedin geline of the wire as where the adjusting-screw 55 is employed. The purpose of the adjustingscrew 21 is to time the movement of the lower feed-roll with the movement forward of the cutter-holder, or, in other words, with the en agement of the cutter with the wire.

In pIace of pivotally supporting the cutterholder upon the stud 14, as shown at Fig. 2, the modification shown at Figs. 21 and 22 could be used. This consists of the reciproeating slide 13 adapted to operate in guideways formed on the front face of the head 2. In this construction the driving-pin 35 is operatively mounted in the projection 13 of the said slide. A spring (not shown) can be used to return this slide back to its normal position, as described, for the pivotallysupported cutterholder, also an adjustable stop (not shown) can be employed to locate the slide in its back or normal position.

It is customary in machines of this character to employ a driving-shaft carrying the driving-pulley and to locate said shaft beneath the head of the machine and operate the cutter-holder from a cam on this shaft. WVith this arrangement there is more vibration imparted to the cutterholder, which shakes and disarranges the fixed parts of the machine. With my present construction the usual driving-shaft is dispensed with and the upper feed-roll shaft 8 becomes the driving-shaft and the second feed-roll 7'is driven by the pinion 70, meshing with the pinion 71 on said shaft 7. Placing the cam for actuating the cutting-off lever on the upper feedroll shaft, the cutter-holder is actuated directly in line with the cutting-off die, so that all shock or jar is entirely eliminated from the machine. It will therefore be readily seen that my present invention possesses many novel features that will be appreciated by users of machines of this character. It is cheaply constructed, readily assembled and taken down for transportation, can be extended to out any length of wire at avery small extra cost, and when the head alone is used the driving-pulley and cutter-holder IIS cam may be dispensed with, and the cutterholder can be operated by means of the handle 7 2, shown (see Fig. 2) in broken view as projecting from a hole in the said holder.
